pre-push check fails on macOS trying to use a Linux jq binary

*Title*: pre-push check fails on macOS trying to use a Linux jq binary

*Description*:
The `./ci/do_ci.sh check_proto_format` script on macOS is attempting to use a Linux `jq` which fails for obvious reasons.

*Repro steps*:
- Fresh clone of `envoyproxy/envoy` on a macOS Apple Silicon host
- Setup git hooks as documented via `./support/bootstrap`
- Create a branch and push a dummy commit

*Logs*:

Start with ci/do_ci.sh check_proto_format and tools/proto_format/BUILD, then inspect how the jq tool is selected during the macOS Apple Silicon build. Reproduce the failure with ./ci/do_ci.sh check_proto_format after ./support/bootstrap; done means the check completes successfully on that host without attempting to execute an incompatible Linux jq binary.
